' BOTTLE-CLOSURE.

Specification of Letters Patent.

Patented Oct. 12, 1920.

Application filed December .28, 1918. Serial No. 268.654.

county, and State of New York. have invented certain new and useful Improvements in Bottle-Closures, of which the following is a specification.

This invention relates to new and useful improvements in bottle closures and more particularly to that type designed for repeated home use in milk and cream bottles.

The main objects of the invention are to provide a device of a highly sanitary character that will remain efficient in long continued use, and serving to ornament the bottle when inserted in position; the invention embodies also simplicity in assembly and dis'assembly and economy in construction.

These and further objects of the invention will be more fully understood from the following description and by reference to the accompanying drawing in which- Figure 1 is a side elevation of one form of the invention;

Fig. 2 is a central sectional elevation of the same, showing the invention in position in the mouth of a milk bottle;

Fig. 3 is a top plan view of Fig. 1; and

Figs. 4, 5 and 6 'ing commercial milk bottles having the largest recess 5 in the mouth thereof. Such recess 5 is usually concave, adjacent the extreme edge of the mouth, as indicated in Fig. 2.

The tapering or upwardly and outwardly flaring relation of the projecting portion or lip 4 relative to the central portion of the closure disk 1, enables the lip or projecting portion 4 to be easily forced into bottles of minimum diametrical recessand to accomare respectively detail; central sectional elevations of the three modate itself to bottles of larger diametrical recess. The closure disk 1 is further provided with an opening 7, adapted to receive the neck 8 of thespout 9. The enlargement 10 at the lower neck portion of the spout 9 corresponds in contour to the rounded edge 11 of the opening 7 in the closure disk 1 and serves to hold the spout firmly in place when the closure disk is stretched thereon. The spout 9 is provided in the rear of its rim with an elongated slot 12, adapted to receive loosely the reduced portion .13 of the cover 14, thereby combinedly forming a hinge for the cover 14. The reduced and upwardly extending portion 15 of the cover 14 serves as a finger piece for manual manipulation.

It may be observed from the foregoing that the particular type of the preferably three piece construction,v as shown, is extremely simple and that the nature of the parts is such that theymay be easily made from light weight and inexpensive material.

It will be further noted that the hinged relation of the cover is effected without the usual hinge pin, by the simple and economical arrangement of assembly, as shown. It will be readily seen that the entire assembly is accomplished by simply passing the finger portion 15 and the reduced portion 13 of the cover 9 and the introduction of the neck 8 of the spout 9 into the opening 7 in the closure disk 1. The invention as a whole is of an exceptionally sanitary character, inasmuch as the surfaces exposed to the fluid contents of the bottle are easily cleansed; the facility with which the several parts can be disassembled and re-assembled renders the bottle closure to be the more effectually cleansed, since the parts may be occasionally entirely taken apart and cleansed separately.

A further sanitary advantage of the device lies in the feature of the entire pouring surface of the spout being fullyprotected by its cover when in closed position.

In practical use, the conformation of the 14 through the slot 12 in the spout resilient periphery of the closure disk combined with its comparatively rigid central part insures a frictional fit in bottles having mouth recesses of varying diameters and at the same time permits the closure diskto be manually introduced or removed with case. It will be noted that the flexible lip accommodates itself, and thereby the closure disk as a whole,

to frictionally fit the mouth openings of diifer ent sizes of bottles and as Well to irregularities in the manufacture of the bottles.

Such frictional fit of the closure disk also insures against leakage of the fluid contents of the bottle when inv without departing from the invention and.

the scope o I claim. 1. In a bottle closure, a frictional. disk the appended claims.

provided with an opening and having a yieldable periphery, a pouring spout provided with an elongated slot, a cover for said spout, said cover being retained in hingeable'relation when a reduced portion of same is entered into said elongated slot and the neck of the said pouring spout is positioned in said opening in said disk.

2. In a bottle closure, a frictional disk of yieldable material having a thickened and positioning said spout within said opening,

a cover for said spout and means for hinging said cover to said spout, said last named means comprising an elongated slot disposed in the rim of said spout, said cover aving a reduced portion extending through said slot.

In testimony whereof I have si ned this specification this 21st da of Decem he'r, 1918. WILLIXM W. HARRIS.
